scription of the invention, such as wil en-A able others skilled in the art to which it appertains to inake and use the same.

This invention relates to improvements in hubs for autoinobile or other vehicle wheels. One object of the invention is to provide a hub having springs suitably arranged therein whereby a resilient support is provided for the veliicle which is designed to take the place of a pneumatic tire.'

Another object is to provide a hul. of

this ,:haractei` which will be simple, strong and durable in construction, ellicient in operation and well adapted to the purpose for which it is designed.

lVilh these and other objects in vfiew, the invention consists of certain novel features of construction, combination andarrangement of parts as will he more fully described and particularly pointed out m the appended claims.

In the accompanying drawings: 4Figure l Qis a central vertical longitudinal section of my improved huh; Fig. 2 is a central horizontal sectional view thereof; Fig. 3 is an inner end view of the saine; Fig. 4 is a vertical cross sectionalview on the line 4-4 of I"ig.2; I `ig.'5isasimilar view on the line 5-5 of Fig.2; Fig. 6 is a similar view on the line 6.*6 of Fig. 2; Fig. 7 is a detail view of the har or link forming pai-t of the universal joint connection between the shaft and hub; Fig.- 8 is a perspective view of the outer end of the axle and the joint socket thereon.

Irleferring more particularly to the drawings, 1 denotes the front end, 2 denotesY the central portion and 3 denotes the inner end of the outer casing of the hub.` The front end of the casing is tapered toward its outer end as shown at 4 and has its inner end engaged with and rigidly secured to the front end of the central portion of the casing, said end of the central portion projccting into the front portion as shown. 0n the inner end of the front portion l is formed an annular radially projecting flange 5 which forms one side of the spoke receivresidinfv ing channel (1in which thespokes of the wheel are secured.

The inner portion 3 of the 'casing is tix.-

edly engaged with the inner end ofthe ccntral portion 2 and on the inner end of said portion 3 is torined an annular radially pro-i jecting flange 7 which cosaets with the [lange 5 and Vforms the other side of the spoke s channel 6. The outer'ciid of thc'central por- .65

tion 2 of the casing is interiorly threaded as at 8 and into said threaded end is screwedil an adjusting ring 9 having on its outer side.

diametrically disposed lugs 10 provided with threaded apertures in which are arranged set screws 11 adapted to be screwedinto engagement with the adjacent inner-j sides of the casing 3 whereby 'the 4ring isi locked in its adjusted positions. The central portion 2 of the casing has formed on its inner end an annular inwardly .a projecting stop flange 12A between which and the adjust-ing ring 9 is arranged the inner spring holding an axle receiving member 13 of thehub. The member 13 coin'- prises a cylindrical sleeve or thimble 14 in whichis arranged a hollow head'15 formed in two substantially semi-cylindrical sec-"- tions 1Gwhich are spaced apart to forni a'4 aide passage 17 and which closely e opposite sides of the thimble as' vertical engage t shown.

The sections of the head are held apart at their, upper sides to form the passage 17 by a spacing block 18 as shown.

Slidably mounted 'in the passage 17 between the sections of the head is a journal block or boxv 19 with' which is revolubly engaged the axle 20 of the vehicle. .On the upper end of the block 19 are formed lugs 21 which project laterally between the opposite ends of the head sections and slidably engage ihe saine. On the inner side ofthe lugs 2l are formed studs 22 with which are en'- gagcd the upper ends of coiled axle supporting springs 23 the lower ends of which are engaged with studs 24 arranged on supporting blocks 25 in the lower portions of the head sections as shown. Any number of spi-ings 23 inay he employed two of the saine being shown in the present instance o'n each are reduced to form vertical guide flanges 27 which are adapted to slidabl engage vertical guide passages 28 forme in the end of the axle bolster 29 or other stationar portion of the vehicle running gear where y the spring holdi-n and axle engaging member pif lthe hub is eld against turning with the u Y e On the outer end of the axle adjacent to the outer side of the head sections 1s fixedly mounted a socket 30 formin one member of a universal joint connection tween the axle and the outer end of the hub casing 1. In the socket is formed a cross shaped recess 31 with which is loosely engaged the cross shaped inner end of a connecting bar or link 32 the outer end of which is similarly shaped and engaged with a cross shaped recess 33 formed in a cap 34 screwed on the outer end of the section 1 of the casing. The connecting bar 32 when thus arranged forms a universal joint connection between the hub and the axle whereby these parts will turn together without interfering with the action of the springs which form the yielding support for the axle and vehicle. When the axle is not intended to turn with the hub the connecting bar or link 32 ma be removed. In the outer tapered end o the hub casi 1 is formed an oil hole 35 through which o1 is introduced to the casing to lubrieate the axle and joint connection hereinbefore described. The 'hole 3,5 is normally closed by a. screw plug 36.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without re uiring a more extended explanation.

arious chan es in the form, proportion and the minor etails of-eonstruction may be resorted to without departing from the principle or sacrificing an of the advantages of this invention, as elined in'the appended claims.Y Having thus described my invention, what I claim is:-

outer casing, an axle receiving member arranged in said casing, a journal block slid-V ably mounted in said member to receive the end of the axle, springs engaged with said block, whereby sald block and the axle are supported, adjustable means to hold said axle receiving member against lateral movement, means to hold said axle receiving member against rotation, and means to loosely connect the outer end of the axle with the outer casing of the hub, whereby said a'xle and easin are revolved together. l 2. A hub for vehicle wheels comprising an outer casing, an axle receiving member, said member eomprisin a sleeve, a head ar ranged therein, said head comprising twehollow substantially semi-circular sections. \a 'ournal block slidably mounted between said head sections and adapted to receive the end of the axle, laterally projecting lugs formed on the opposite sides of said block and having a sliding engagement with said sections, spring supporting blocks arranged in th lower portion of said sections, springs arranged between said lugs and the blocks in said sections, adjustable means to hold said axle receiving member against lateral movement, means to hold the same against rotation, and means to loosely connect the outer end ofthe axle with the outer casing of the hub whereby said axle and casing will revolve together.

3.` hub for vehicle wheels comprising a casing consisting of a central and end portions, said end portions engaging said central portion and havin formed on their inner ends annular radia ly projecting flanges adapted to form an annular spoke receiving channel, an annular inwardly extending flange formed on the outer end of said eentral `portion of the casing, an axle recel-ving member arranged in said easing and engaging said flange,l an adjusting ring havin a screw threaded engagement with the outer end of said central portion of the casina whereby said axle receiving men'xber lieti against lateral movement, set screws to lock said ring in its adjusted position, and a mounted in said axle receiving member.

In testimony whereof I have hereunto set r my hand in presence of two subscribing wit- 1. A hub for vehlcle wheels comprising an A Y nesses. Y
